Castledermot Round Tower is a 10th-century round tower in Castledermot, County Kildare, Ireland. The tower, and the high crosses nearby, are a National Monument.
The tower is complete, although the original cap has been replaced with battlements. It is composed of rounded granite boulders embedded in mortar.
Castledermot was founded as a monastic settlement c. 800 AD. The bishop-poet Cormac mac Cuilennáin was buried here in AD 938 and the round tower was probably built around that time. The community ceased to exist some time after 1073.
